Since I'm still stuck in a non-writerly place, I'll keep offering you bits of my favorite hobby these days... photography.
Here's a robin I snapped last night. I call him Bob. (As in, the red, red robin goes Bob-bob-bobbin' along.)
And here's a shot of Mrs. Downy Woodpecker. (I call her Roberta. Yes, not seemingly original until you realize her full name is Roberta Downy Woodpecker - which makes her mate Robert, naturally.)
